(54) Electric precipitator


(57) An electric precipitator (10) includes a charge unit (10A) disposed at an upstream part and a dust collection unit (10B) disposed at a downstream part, the charge unit (10A) includes charge electrodes (11) and a discharge wire (14) disposed between two neighboring charge electrodes (11) and separated from the charge electrodes (11), the dust collection unit (10B) includes high voltage electrodes (12), front ends of which are opposite to the charge unit (10A), and low voltage electrodes (13), front ends of which are opposite to the charge unit (10A) and which alternate with high voltage electrodes (12), and the front ends of high voltage electrodes (12) protrude toward the charge unit (10A) as compared to the front ends of low voltage electrodes (13), thereby guiding electrons to the discharge electrodes (14) due to an electric field formed between the front ends of the high voltage electrodes (12) and the discharge electrodes (14) and thus reducing current leakage through the low voltage electrodes (13).
